Make it so we can switch them. I tend to misclick and accidently ratedown posts on mobile. It won't take long to implement.
2 Solutions To Prevent Spamming
1) Add a timer of one minute. Players can switch between up or down within that time and when it is over you will not be able to switch.
2) You can only switch the rates twice.
When you do change your rate then it goes back to the top of the player's feed with something like
xxx rated you up instead.
xxx rated you down instead.
